All’s been quiet on the Amanda Bynes front since she set that fire in that old woman’s driveway and was taken in on a 5150 psychiatric hold, where she will remain for at least the next three weeks or so, since doctors at the Hillman Psychiatric Center in Ventura County were successful in extending the hold for another 30 days as of last week.

Apparently, Amanda’s suffering from Post-Traumatic Stress Disorder (PTSD) and is undergoing treatment for it, but there’s a long road ahead of her in order to get back to a functional place where she’s no longer a danger to herself or others.

“Amanda has made significant improvements, she is doing better than she was,” an insider told FOX411’s Pop Tarts column. “There are no drug problems involved, it’s all mental. She has deep anger and PTSD, which tripped a psychotic episode… She is very ill, but manageable. Amanda genuinely wants to get better and has wanted to get better for some time.”

We’re also told that Bynes agreed to stay for the extended 30 days the night before the court hearing, as her team expressed concern she may try to leave treatment sooner than what would be appropriate without the court’s involvement.

“She is easy to deal with at the moment and agreed to stay,” continued the insider. “While she is doing much better, Amanda needs to be monitored. She is on heavy anti-psychotic drugs and that requires constant medical observation. She wasn’t able to attend the hearing on Friday because at this point in treatment, she should not be moved.”

Aw, I’m really glad she wants to get better and seems to be on the road to doing so. She’s obviously fucked up and got involved with some messed up shit, but it’s hard to see anyone suffering the way she has – self-inflicted or not – and I hope she manages to confront her issues and tackle them so she can start to enjoy living her life again – even if that’s one OUTSIDE of Hollywood (which would probably just bring all the old issues right back again).
